If you teach technology and haven't looked at this site, go check it out. It has videos, a forum, webinars, and an online magazine that you can subscribe to (it is sent to your e-mail) among many other things. It is well worth the look.

This is an interesting website to help your students understand how to evaluate websites for use in research. It is also available in PDF format.
